Why is it that whenever i get attacked by a monster in the cave it does 1 damage but when i get attack by a bunch of monsters it's like their attack stacks and they do over 15 damage. Supposed to stack?

When you are attacked by multiple enemies both your defence and your evade probability go down. If that behavior is supposed to be that way or not is not under our control as we didn't program the server. After we switched to TMWServ you may ask again if whatever behavior you see ingame is how it is supposed to be, a bug or just your imagination.

You might have heard a certain rumor about me. This rumor is completely false. You might also have heard the other rumor about me. This rumor is 100% accurate.

Even if only one monster is attacking, they will occasionally score a "critical" on you, which is like a regular hit, only it ignores all your defence. If you're heavily armored, that can come as quite a shock. Certainly more of a chance of this happening, when being attacked by multiple foes. Also standard RO (eAthena) behavior.
